DETAILED DESCRIPTION

[0019] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific embodiments, structures, features and effects according to the present application are described in detail as follows in combination with the drawings and preferred embodiments. ​

[0020] Referring to Figures 1-5 As shown in the drawings, the present application provides a photovoltaic module with windproof function, which comprises a counterweight seat 1 installed on a base, four outer surfaces of the counterweight seat 1 are provided with photovoltaic side plates 3 capable of adjusting the angle simultaneously, the bottom of each photovoltaic side plate 3 is hinged to the base, and the back of each photovoltaic side plate 3 is provided with a plurality of positioning grooves 11; The inside of the counterweight seat 1 is provided with an adjusting unit for simultaneously rotating each photovoltaic side plate 3, the lower part of the adjusting unit is provided with a plug-in unit for positioning the back of the photovoltaic side plate 3, and the inside of the counterweight seat 1 is provided with a power switching unit which can be raised and lowered; The adjusting unit comprises four threaded rods 10 which rotate simultaneously, the outer surface of each threaded rod 10 is threadedly connected with an upper sleeve 9, the upper end of the upper sleeve 9 is hinged to a transmission rod 8, and the end of each transmission rod 8 away from the upper sleeve 9 is hinged to the back of the corresponding photovoltaic side plate 3; The plug-in unit comprises four threaded rods 16 which rotate simultaneously, the outer surface of the end of each threaded rod 16 away from the inside of the counterweight seat 1 is threadedly connected with a lower sleeve 15, and the lower sleeve 15 is slidingly arranged with a slide rod outside the counterweight seat 1; The upper surface of each lower sleeve 15 is hinged to a plug-in rod, a torsional spring is arranged between the plug-in rod and the lower sleeve 15 for providing a rebound force, the outer side of the plug-in rod is provided with a pushing part 13 fixedly connected with the lower sleeve 15, the pushing part 13 is provided with a synchronous electric cylinder for pushing the plug-in rod, and the torsional spring is used for providing a rebound force for the deflection reset of the positioning rod 12; When the power switching unit is raised, it is connected with the adjusting unit to simultaneously adjust the angle of the plurality of photovoltaic side plates 3; When the power switching unit is lowered, it is connected with the plug-in unit to change the plug-in angle of the plug-in rod, so that the plug-in rod after the change of the plug-in angle enters into the corresponding positioning groove 11; In use, the photovoltaic module takes the counterweight seat 1 as a bearing main body, and the photovoltaic side plates 3 are installed in four directions outside the counterweight seat 1, the bottom of the photovoltaic side plate 3 is hinged to the base, so that the photovoltaic side plate 3 can be arranged in a surrounding manner; When external wind force acts from different directions, the photovoltaic side plates 3 simultaneously realize synchronous adjustment of the angle through the adjusting unit; that is, the power switching unit is in a raised state and is engagedly connected with the adjusting unit, the four threaded rods 10 in the adjusting unit rotate simultaneously under the drive, the threaded rods 10 drive the upper sleeves 9 threadedly connected with the outer surface of the threaded rods 10 to move in the axial direction; the axial movement of the upper sleeves 9 pulls the corresponding transmission rods 8, and then transmits the pulling force to the back of the photovoltaic side plate 3, thereby driving the four photovoltaic side plates 3 to synchronously rotate around the hinge point of the bottom of the photovoltaic side plate 3 and the base, realizing simultaneous adjustment of the overall angle of the plurality of photovoltaic side plates 3, and ensuring the consistency of light utilization; The photovoltaic side plate 3 maintains a large inclination angle to ensure that the front side faces the sunlight and improve the light utilization rate, and the wind pressure is small, so that the module can remain stable; when the inclination angle of the photovoltaic side plate 3 is moderately reduced, the windward area is reduced, the light utilization is ensured, and the wind load is reduced, thereby avoiding shaking of the module; Then, the power switching unit is connected with the plug-in unit when it is lowered, so that the four-direction threaded rods 16 rotate at the same time. At this time, the lower sleeve 15 moves axially along the slide rod direction. In this process, the plug-in rod is pushed by the synchronous electric cylinder on the pushing part 13, so that the plug-in rod deflects around the hinge point of the lower sleeve 15, changes the plug-in angle of the plug-in rod, and is reliably locked under the cooperation of the plug-in rod and the positioning groove 11, thereby effectively preventing the wind from causing concentrated impact on the photovoltaic side plate 3 from any direction, and improving the overall wind resistance stability. After the photovoltaic side plate 3 completes the angle adjustment and is locked by the plug-in rod inserted into the positioning groove 11, a stable ring-shaped multi-direction wind resistance structure is formed. When external wind force acts from different directions, the photovoltaic side plate 3 can maintain a stable angle, avoid shaking, deviation or falling due to wind pressure concentration, and the weight of the counterweight seat 1 further enhances the overall stability, thereby effectively resisting wind impact and preventing wind force from different directions, achieving omnidirectional wind resistance protection.

[0021] Referring to Figure 3 As shown, the plug-in rod includes a long positioning rod 12, and the end of the positioning rod 12 is connected with a touch part 14 in contact with the pushing end of the synchronous electric cylinder. After the touch part 14 is in contact with the pushing end of the synchronous electric cylinder, the positioning rod 12 rotates around the hinge point. During the plug-in action, when the lower sleeve 15 moves to the predetermined position along the slide rod direction, the synchronous electric cylinder on the lower sleeve 15 is started, the pushing end extends outward and is in contact with the touch part 14 at the end of the positioning rod 12. Under the action of the pushing force, the touch part 14 transmits the external force to the positioning rod 12, so that the positioning rod 12 rotates around the hinge point with the lower sleeve 15, thereby changing the plug-in angle of the positioning rod 12. During the rotation process, the positioning rod 12 has a rebounding property under the constraint of the torsional spring. When the synchronous electric cylinder is retracted and the external force is removed, the positioning rod 12 can be returned to the original position under the action of the torsional spring. In this way, the positioning rod 12 can be reliably inserted into the positioning groove 11 at the back of the photovoltaic side plate 3 when needed, and automatically restored to the initial position when not needed, thereby avoiding jamming and achieving accurate control of the angle of the positioning rod 12 and ensuring the stability of the plug-in action.
